Kano Model Overview

::

The Kano model is a framework for understanding customer needs and preferences developed by Professor Noriaki Kano in the 1980s. It is used in product development and customer satisfaction management to prioritize features and attributes that contribute to customer satisfaction.

The model classifies customer preferences into five categories:

• Basic Needs (Must-Have): These are essential features that customers expect and take for granted. Their absence leads to dissatisfaction, but their presence doesn’t necessarily provide satisfaction—they are just baseline requirements.

 

• Performance Needs (More is Better): These are features that, the more you have of them, the more satisfied customers will be. However, their absence doesn’t necessarily lead to dissatisfaction.

 

• Excitement Needs (Delighters): These are unexpected features that, when present, can generate high levels of satisfaction. Customers may not explicitly request them because they are often beyond their expectations.

 

 

• Indifferent Needs: These are aspects of a product that do not significantly impact customer satisfaction, whether they are present or absent.

 

• Reverse Needs (Dissatisfiers): These are features that, when present, lead to dissatisfaction, but their absence doesn’t necessarily result in satisfaction. These are often things that customers assume will not be an issue, and if they are present, they become sources of dissatisfaction.

The Kano model is often represented graphically as a two-dimensional graph, where the x-axis represents the level of a particular feature or attribute, and the y-axis represents customer satisfaction. Understanding the categorization of features based on the Kano model can help businesses make informed decisions about product development and prioritize features to enhance customer satisfaction.

Steps:

• Identify Customer Needs:
  • Conduct customer surveys, interviews, or focus groups to gather information on customer needs and preferences. Ask open-ended questions to uncover both explicit and implicit needs.

 

• List and Describe Features:
  • Create a list of features or attributes associated with your product or service. Clearly describe each feature to ensure a common understanding within your team.

 

• Categorize Features:
  • Use the Kano model categories to classify each feature:
    • Must-Have (Basic Needs)
    • More is Better (Performance Needs)
    • Delighters (Excitement Needs)
    • Indifferent Needs
    • Dissatisfiers (Reverse Needs)

 

• Collect Customer Feedback:
  • Present the list of features to a representative sample of your target audience and collect feedback on each feature. Ask customers to rate their level of satisfaction with each feature.

 

• Plot Results on Kano Graph:
  • Create a Kano graph with the x-axis representing the level of a particular feature and the y-axis representing customer satisfaction. Plot each feature based on customer feedback and categorization.

 

• Analyze Results:
  • Analyze the distribution of features on the Kano graph. Identify features that fall into each category (Must-Have, More is Better, Delighters, etc.). Pay attention to features that may be dissatisfiers.

 

• Prioritize Features:
  • Prioritize features based on the Kano model categories. Focus on addressing basic needs to avoid dissatisfaction, enhancing performance needs for incremental satisfaction, and considering the inclusion of delighters for a competitive edge.

 

• Develop Action Plans:
  • Create action plans for product development, improvement, or marketing based on the prioritized features. Allocate resources accordingly, giving higher priority to features that have a significant impact on customer satisfaction.

 

• Implement Changes:
  • Implement the changes or improvements to the product or service based on the action plans. Monitor the effects of these changes on customer satisfaction over time.

 

• Iterate and Update:
  • Customer preferences and market conditions can change, so it’s important to regularly revisit the Kano model analysis. Update your understanding of customer needs and repeat the process to ensure ongoing alignment with customer expectations.

Advantages

Prioritization of Features: One of the key advantages is its ability to help prioritize features. By categorizing features into different types (Must-Have, More is Better, Delighters, etc.), businesses can focus their resources on developing and improving features that have the greatest impact on customer satisfaction.

Customer-Centric Design: Encourages a customer-centric approach to product development. By understanding the different types of customer needs and preferences, businesses can design products that align more closely with customer expectations and deliver a better overall experience.

Resource Optimization: The model helps in optimizing resource allocation by directing efforts toward features that truly matter to customers. This prevents the allocation of resources to aspects that may not significantly impact satisfaction, allowing for a more efficient use of time and resources.

Competitive Advantage: By identifying and incorporating delighters (unexpected features that bring high satisfaction), a company can gain a competitive edge. These surprise elements can differentiate a product from competitors and enhance customer loyalty.

Continuous Improvement: Supports the concept of continuous improvement. As customer needs and preferences evolve, businesses can use the model to reassess and adapt their product development strategies to stay in tune with changing market demands.

Enhanced Customer Satisfaction: Ultimately, the goal of the Kano model is to enhance customer satisfaction. By focusing on features that have the greatest impact on customer perception, companies can create products that not only meet but exceed customer expectations.

Communication and Marketing: The model provides a framework for communicating with customers. By understanding which features are basic expectations, performance-driven, or delighters, companies can tailor their communication and marketing strategies to highlight the aspects that are most likely to resonate with their target audience.

Disadvantages

Simplification of Reality: The Kano model simplifies the complexity of customer preferences into five categories. In reality, customer needs can be more nuanced and context-dependent. The model may not capture the full range of factors influencing customer satisfaction.

Static Nature: The model assumes a static relationship between features and customer satisfaction. However, customer preferences can change over time, and what was considered a delighter in the past may become a basic expectation. The model may not account for evolving market dynamics.

Dependence on Customer Feedback: The accuracy of the model relies heavily on the quality and accuracy of customer feedback. If customers are unable to articulate their preferences accurately or if the feedback is biased, the model’s effectiveness may be compromised.

Limited Guidance on Implementation: While it helps identify and categorize features, it provides limited guidance on how to implement these insights. Businesses may struggle with translating the model’s recommendations into actionable strategies for product development.

Influence of Cultural and Social Factors: The model may not fully account for cultural and social factors that influence customer preferences. What constitutes a delighter or a basic need can vary significantly across different cultures and demographics.

Neglect of Market Trends: May not address emerging market trends or disruptive innovations. It is based on historical customer preferences and may not be well-suited for industries or products undergoing rapid changes.

Subjectivity in Categorization: Categorizing features into the different Kano categories involves a degree of subjectivity. Different individuals within an organization may categorize features differently, leading to potential inconsistencies in the analysis.

Limited Guidance for Competitive Benchmarking: While the model helps prioritize features based on customer satisfaction, it may not provide explicit guidance on how a product compares to competitors. Understanding the competitive landscape requires additional analysis.

Examples

• Must-Have (Basic Needs):
  • Smartphone Connectivity: For a modern car, the ability to connect to smartphones for hands-free calling and music playback is considered a basic expectation. Customers expect this functionality, and its absence would lead to dissatisfaction.

 

• More is Better (Performance Needs):
  • Battery Life in a Laptop: While customers expect their laptops to have a minimum battery life for basic functionality, having a longer battery life is considered a performance need. The longer the battery life, the more satisfied the customer is likely to be.

 

• Delighters (Excitement Needs):
  • Voice-Activated Virtual Assistant in a Smart Speaker: The inclusion of a voice-activated virtual assistant that can perform various tasks beyond basic music playback can be a delighter. Customers may not have explicitly asked for it, but its presence can greatly enhance satisfaction.

 

• Indifferent Needs:
  • Packaging of a Consumer Product: The design or color of the packaging for a product may not significantly impact customer satisfaction. In many cases, customers are indifferent to the packaging as long as the product inside meets their expectations.

 

• Dissatisfiers (Reverse Needs):
  • Software Bugs in a Mobile App: If a mobile app frequently crashes or has significant bugs, it can lead to dissatisfaction even if the app has other valuable features. The presence of these issues can override the positive aspects of the app.
